CCS/LAUNCHXL-CC1310: hex file format

Part Number: LAUNCHXL-CC1310

Tool/software: Code Composer Studio

Hi,

I'm developing using CCS. Here is a hex file built with CCS (rfEasyLinkTx example).

I want to know what is in front of each line. I'm not sure, but I guess.

:0CA1F400 0A0000002018002011660000 86

0C A1F4 00 0A0000002018002011660000  86
row data length address (?) row data (crc?)

I want to know :

1) header format of hex file (front of each line)

2) the meaning of line 1297 and 1301 in the above figure.

3) the end of each line looks like crc, if so, what is the crc calculation method?

4) is there a crc for the entire hex file

regards,

taehee.
